Answer:

<h2>a = 2 and b = 6.</h2>

Step-by-step explanation:

The equation is given by 10x - 4 = ax + b\\(10 - a)x = 4 + b\\x = \frac{ 4 + b}{(10 - a)}.

The given equation is a one degree polynomial, hence it has only one solution whatever the value of a and b will be.

If the value of a is 10, then the solution of the equation will be undefined.

Hence, a is any real number rather than 10.

As for example, a = 2 and b = 6.

Find the equation of the line passing through the points 7,2 and 9,1
bija089 [108]

9514 1404 393

Answer:

  y = -1/2x +11/2

Step-by-step explanation:

The slope of the line is ...

  m = (y2 -y1)/(x2 -x1)

  m = (1 -2)/(9 -7) = -1/2

The y-intercept is ...

  b = y -mx

  b = 2 -(-1/2)(7) = 11/2

Then the slope-intercept equation is ...

  y = -1/2x +11/2

_____

<em>Alternative solution</em>

A general form equation for the line can be ...

  (y1 -y2)(x -x1) -(x1 -x2)(y -y1) = 0

  (2 -1)(x -7) -(7 -9)(y -2) = 0

  x-7 +2y -4 = 0

  x +2y -11 = 0 . . . . . general form equation

  x +2y = 11 . . . . . . . standard form equation

Note that we want the x-coefficient to be positive, so we chose the order of the points to make that be the case.

Answer:

Stain required to stain the ramp = 2 quarts

Step-by-step explanation:

Area of the wheelchair ramp to be stained = Surface area of the ramp - Area of the rectangular base

Surface area of the ramp = 2(area of the triangular base) + (perimeter of the base)(height)

Area of the triangular base = \frac{1}{2}(\text{Base})(\text{Height of the triangle})

                                             = \frac{1}{2}(25)(\frac{25}{12})

                                             = \frac{625}{24} in²

Perimeter of the triangular base = 25\frac{1}{12}+25+\frac{25}{12}

                                                      = 25 + \frac{1}{12} + 25 + \frac{25}{12}

                                                      = 50 + \frac{26}{12}

                                                      = 50 + 2+\frac{2}{12}

                                                      = 52\frac{1}{6} ft

Surface area of the ramp = \frac{625}{12} + (52\frac{2}{12})\times 5 - 25×5

                                          = \frac{625}{12}+\frac{3130}{12}-125

                                          = \frac{3755}{12}-125

                                          = 187.92 square feet

Since, 100 square feet area is covered by the stain = 1 quart

Therefore, 187.92 square feet will be covered by the stain = \frac{187.92}{100}

= 1.8792

≈ 2 quarts
